These are the questions that have me wondering...

exactly! If it's on the Mac OS X disk will it interfere with using the 
Mac as a Mac only? Isn't yaboot the tiny piece of software that gets 
stuck in the MBR?  If  it's on the Mac  hdd  I would expect it to  
continue offering me a choice of  booting into Mac or Linux even after 
the Linux  disk  is nowhere to be found!

Right now yaboot will boot through to YDL unless I type "x" when yaboot 
appears. That suggests to me that yaboot is on the Mac disk because 
sometimes that's where the whole process stops...I suspect because they 
YDL disk can't be found!

When I say 'set OS X as my boot disk I'm referring to the "startup disk" 
as you mentioned above!

When all this is done with I think I will stay away from dual boot 
systems and perhaps get myself a G3 clamshell just for YDL! I originally 
got started with YDL on a PPC 5500 with a G3 upgrade processor, but 
found YDL couldn't take advantage of the processor upgrade so the PPC 
5500 is sitting out in the garage.

Thanks for response, Eric.
